This function masks valid credit card numbers and keeps the Bank Identification Number/Issuer Identification Number (BIN/IIN). The output value is a valid credit card number.
This function:
  • keeps the first six digits,
  • masks the other digits and
  • generates the last digit using the Luhn algorithm.

Two methods are available: FF1 with AES and FF1 with SHA-2. This function requires no alphabet and no extra parameter.

In the following example, the Keep format check box is selected to preserve the space from the input value.
